Anthurium plant named 'ARAANTRED1'

Abstract

`ARAANTRED1` is a new and distinctive variety of Anthurium which is characterized by the combination of a vibrant red, glossy spathe with a nearly horizontal aspect and a relatively short spadix which is colored white with a yellow apex, an abundance of narrowly cordate foliage which is dark green and glossy, inflorescences held above the foliage, and the stability of all characteristics from generation to generation. The new variety is typically produced as an indoor ornamental plant.

1. A new and distinct variety of Anthurium plant named `ARAANTRED1`, substantially as described and illustrated herein.
Description



CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to the Community Plant Variety Rights application number 2016/0699, filed Mar. 10, 2016, which is herein incorporated by reference.

[0002] Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Anthurium andraeanum Linden ex Andre.

[0003] Variety denomination: The inventive variety of Anthurium disclosed herein has been given the variety denomination `ARAANTRED1`.

BACKGROUND OF THE INVENTION

[0004] Parentage: The new cultivar is a seedling selection which resulted from the controlled pollination of Anthurium andraeanum `K37`, the seed parent, and Anthurium andraeanum `K38`, the pollen parent. Both parents are developed and owned by the inventor and were never commercially released. Said cross was performed by the inventor in De Lier, The Netherlands, in June of 2013. Seeds were harvested from `K38`, sown, and grown to maturity in order to evaluate for unique characteristics which may be of commercial value. In September of 2014, after evaluating the seedlings for approximately one and a half years, one progeny was observed to exhibit good plant vigor with a unique combination of vibrant red, glossy spathes and an abundance of attractive narrowly-cordate foliage. In December of 2014, after further evaluation to confirm the unique characteristics, the new cultivar was selected for commercialization and given the breeder denomination `ARAANTRED1`.

[0005] Asexual Reproduction: Asexual reproduction of `ARAANTRED1`, by way of meristematic tissue culture, was first performed in December of 2014 at a laboratory in De Lier, the Netherlands. Four successive generations so produced have shown that the unique features of the instant cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

[0006] The cultivar `ARAANTRED1` has not been observed under all possible environmental conditions and the phenotype may vary somewhat with variations in the instant environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following characteristics have been repeatedly observed and represent the distinguishing characteristics of the new Anthurium cultivar `ARAANTRED1`. These traits, in combination, distinguish `ARAANTRED1` as a new and distinct cultivar. [0007] 1. Anthurium `ARAANTRED1` is a robust, moderately vigor herbaceous perennial with a broad, upright growth habit; and [0008] 2. Anthurium `ARAANTRED1` exhibits an abundance of relatively small narrowly-cordate leaves which are dark green and glossy; and [0009] 3. Anthurium `ARAANTRED1` exhibits inflorescences held above the foliage; and [0010] 4. Anthurium `ARAANTRED1` exhibits an inflorescence comprised of a vibrant red, glossy spathe and a relatively short spadix with a rounded apex; and [0011] 5. Anthurium `ARAANTRED1` exhibits a spathe that maintains its vibrant red color for a relatively long period of time before fading.

BRIEF DESCRIPTION OF THE FIGURES

[0012] FIG. 1 shows, as nearly true as it is reasonably possible to make the same in color illustrations of this type, an exemplary plant of `ARAANTRED1`, grown in a greenhouse in De Lier, the Netherlands. The plant shown is approximately 1 year old from a rooted cutting, potted into a 14 cm nursery pot.

[0013] FIG. 2 shows, as nearly true as it is reasonably possible to make the same in color illustrations of this type, the typical foliage of `ARAANTRED1`.

[0014] FIG. 3 shows, as nearly true as it is reasonably possible to make the same in color illustrations of this type, the typical inflorescence of `ARAANTRED1`.

[0015] The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

BOTANICAL DESCRIPTION OF THE PLANT

[0016] The following is a detailed botanical description of a new and distinct variety of Anthurium known as `ARAANTRED1`, based upon observations made from a sample set of plants grown in 9 cm nursery pots which were approximately one year old from a rooted cutting. Plants were grown in a greenhouse in De Lier, The Netherlands, utilizing conventional greenhouse production protocols for Anthurium, which consisted of regular irrigation by way of ebb and flood watering benches and fertilizer applications of a complete fertilizer with micro nutrients at an EC value ranging from 1.0 to 1.8. No chemical pest or disease measures were utilized in production. Young plants are assimilated to the greenhouse under shade cloth and later move to light levels ranging from 3000 to 4000 lux for the final 5 months of production. Observation data was recorded in February of 2017.

[0017] Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. `ARAANTRED1` has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such measurements are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climactic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, sixth edition.
